I've got a Nest and Protect and like them a lot.
This is great news in my opinion, because the only thing that has been missing from it has been lack of enhanced customization.

Heck- they showed a Nest thermostat on an episode of How I Met Your Mother, that had a different font type than the one it has and people got super excited about it over the Internet and then pissed when it turned out not to be a feature available in there next update.

They clearly know that there's a huge interest for customized options, but at this point I don't think they had the support, staff, and resources to devote time to this. With Google, the enhancements, and everything else will get the full treatment for sure!
